r^2 - 2r^3 + 3r^2 =
4r^2 - 2r^3
or
- 2r^3 + 4r^2
2r^3 - 4r^2.
Combine like terms:
r²-2r³+3r² = -2r³ + 4r²
r^2-2r^3+3r^2
Since r^2 and 3r^2 are like terms, add 3r^2 to r^2 to get 4r^2.
4r^2-2r^3
Reorder the polynomial 4r^2-2r^3 alphabetically from left to right, starting with the highest order term.
-2r³ + 4r²
r^2(4-2r)
-2r^3+4r^2
